I agree with you. There are no promises, just what's available if we go after it. I didn't know we were promised peace and spiritual security.
What I mean by promised peace and spiritual security is that we are promised that no matter what, He will never leave us or forsake us - sounds pretty spiritually secure to me.
You said there are no promises, just what is available if we go after it. That "IF" to me implies that IF we go for it, we're sure to get it. We are promised physical persecution, and physical persecution perpetuates illness and injury, poverty and oppression.
What exactly is available to a Chinese Christian, imprisoned for his faith, who as a result of his stand for Christ has been separated from his family, stripped of his job, removed from his home and subjected to physical torture and emotional abuse? How can he "go after" anything healthy and wealthy, other than the spiritual, of course? How about an Indonesian Christian, chased from his home, friends and family raped and murdered and maimed around him - what is he doing wrong in the way he is going after what is available?
Do you see how the two don't jive? Sure - health and prosperity is always available, but it is not always part of God's plan, no matter how hard we may go after it.
